Basilicata (UK: /bəˌsɪlɪˈkɑːtə/ bə-SIL-ih-KAH-tə, US: /-ˌzɪl-/ -ZIL-, Italian: [baziliˈkaːta]), also known by its ancient name Lucania (/luːˈkeɪniə/ loo-KAY-nee-ə, US also /luːˈkɑːnjə/ loo-KAHN-yə, Italian: [luˈkaːnja]), is an administrative region in Southern Italy, bordering on Campania to the west, Apulia to the north and east, and Calabria to the south. It has two coastlines: a 30-kilometre stretch on the Gulf of Policastro (Tyrrhenian Sea) between Campania and Calabria, and a longer coastline along the Gulf of Taranto (Ionian Sea) between Calabria and Apulia. The region can be thought of as "the arch" of "the boot" of Italy, with Calabria functioning as "the toe" and Apulia "the heel".
The region has a population of 529,897 in an area of 10,073.32 km (3,889.33 sq mi). The regional capital is Potenza. The region comprises two provinces: Potenza and Matera. Its inhabitants are generally known as Lucanians (Italian: lucani), and to a lesser extent as basilicatesi or by other very rare terms.
